Description

Technical Field

[0001] This disclosure relates to an electronic shift control device, and more specifically, to the technology of an electronic shift control device that can switch between manual and automatic shift operations according to the driver's intention and can limit the shift direction travel of the shift lever differently depending on whether it is an automatic or manual shift mode. Background Technology

[0002] Typically, vehicles equipped with automatic transmissions control hydraulic pressure within a shift range set according to the vehicle's speed, thereby causing the transmission gears within the target shift range to operate automatically.

[0003] Automatic transmissions use hydraulic circuits, planetary gears, and friction elements to generate gear ratios to perform shifting, and the control of these components is handled by the transmission control unit (TCU).

[0004] The shift-by-wire (SBW) system in a vehicle's electronic transmission system differs from a traditional mechanical transmission system in that there is no mechanical connection structure, such as a cable, between the transmission and the shift lever. In this electronic system, when sensor values ​​generated by the operation of the transmission mechanism (shift lever, shift button, or shift paddle) are sent to the transmission control unit (TCU), the shifting is electronically controlled based on the signals from the TCU.

[0005] Therefore, the advantage of an automatic transmission based on the SBW system lies in its ease of operation, allowing for easier shifting to modes such as D (Drive), R (Reverse), and N (Neutral) through the electronic shift mechanism, which transmits the driver's shifting intentions to the TCU in the form of electrical signals. Furthermore, automatic transmissions allow for smaller shift mechanisms, thus ensuring more space between the driver and passenger seats.

[0006] The foregoing description of the background technology is only for the purpose of helping to understand the technical background of this disclosure, and does not mean that this disclosure falls within the scope of related technologies known to those skilled in the art. Summary of the Invention

[0007] This disclosure relates to an electronic shift control device capable of switching between manual and automatic shifting operations based on the driver's intent, and limiting the shifting direction travel of the shift lever differently depending on whether it is an automatic or manual shifting mode. This disclosure improves the recognizability of shifting operations during automatic or manual shifting modes, and also improves the merchantability of the product.

[0008] In view of the above, an electronic shift control device includes: a shift hinge connected to a shift lever and configured to rotate together with the shift lever in the shift direction when operated by the driver, the shift hinge having a shift groove formed on one side in the shift direction; and a shift roller unit located on one side in the shift direction and mounted to contact the shift groove by a spring force. During rotation of the shift hinge in the shift direction, the shift groove and the shift roller unit remain in contact.

[0009] The electronic shift control device includes: a selection hinge configured to cover the shift hinge and rotate together with the shift hinge in the selection direction when the driver operates the shift lever; a cover bracket configured to cover the selection hinge; and a selection guide attached to one side of the selection hinge in the shift direction. When positioned on the selection hinge, the shift roller unit is mounted such that one end contacts the shift slot and the other end is supported by the selection guide.

[0010] The shift roller unit includes: a shift guide, mounted to move between a shift slot and a selection guide in the shift direction; a shift roller, rotatably coupled to one side of the shift guide and mounted to contact the shift slot; and a shift spring, mounted at an opposite end supported by the other side of the shift guide and the selection guide, and configured to apply a spring force to maintain the contact state between the shift roller and the shift slot.

[0011] The electronic shift control device further includes: a shift protrusion configured to project in the shift direction to the other side of the shift hinge; a travel brake mounted on the selection hinge to be rotatable about a brake axis at an end facing the shift protrusion and having a travel groove on a surface in the shift direction to receive or release the end of the shift protrusion, the travel brake being configured to limit the shift direction travel of the shift lever differently depending on the automatic shift mode and the manual shift mode; and a brake spring mounted to be supported by the travel brake when fixed to the selection hinge and configured to return the travel brake by spring force.

[0012] The electronic shift control device further includes: a shift solenoid, fixedly connected to the cover bracket on the other side in the shift direction, and configured to operate upon receiving an automatic shift mode signal or a manual shift mode signal; and a travel limiter, a second solenoid rod connected to the shift solenoid, and configured to insert into or withdraw from the brake slot and disengage from contact in the travel brake when the shift solenoid is operated, the travel limiter being configured to restrict rotation of the travel brake in the shift direction when inserted into the brake slot, and to release the restriction on rotation of the travel brake in the shift direction when withdrawn from the brake slot and disengaged.

[0013] The electronic shift control device further includes: a shift controller, fixed to a cover bracket, and configured to control the shift solenoid based on a mode selector signal and a clutch pedal signal generated by the operation of the clutch pedal.

[0014] The shift groove includes: an inner groove, formed as a recessed groove at the middle of a surface of the shift hinge; an outer groove, formed as a recessed groove on each of the upper and lower sides of the inner groove; and a protrusion disposed between the inner groove and the outer groove to connect the inner groove and the outer groove, and having a cross section protruding from the inner groove and the outer groove.

[0015] The brake groove is provided on the bottom surface of the travel brake. In the automatic shift mode, the upper end of the travel limiter is inserted into the brake groove. In the automatic shift mode, when the shift hinge rotates in the shift direction due to the shift lever operation, the shift protrusion contacts the side wall of the travel groove, thereby limiting the shift lever rotation in the shift direction.

[0016] The shift controller is configured to control the shift solenoid to insert the travel limiter into the brake slot when an automatic shift mode signal is generated by the operation of the mode selector.

[0017] A brake groove is provided on the bottom surface of the travel brake. In manual shift mode, when the travel limiter is lowered by the operation of the shift solenoid, the travel limiter is pulled out of the brake groove and disengaged. In manual shift mode, when the shift hinge rotates in the shift direction due to the shift lever's shift direction operation, the travel brake is pressed by the shift protrusion and rotates in the shift direction, thereby allowing the shift lever to rotate in the shift direction.

[0018] The brake slot is located on the bottom surface of the travel brake. When both a manual shift mode signal generated by the operation of the mode selector and a clutch pedal signal generated by the operation of the clutch pedal are present, the shift controller is configured to control the shift solenoid to pull the travel limiter out of the brake slot and disengage it.

[0019] A brake groove is provided on the bottom surface of the travel brake. When a manual shift mode signal is generated by the operation mode selector and no clutch pedal signal is generated because the clutch pedal is not operated, the shift controller is configured to control the shift solenoid to insert the travel limiter into the brake groove, and when the shift hinge rotates in the shift direction due to the shift lever's shift direction operation, the shift protrusion contacts the side wall of the travel groove, thereby limiting the shift lever's shift direction rotation and preventing further manual shifting.

[0020] In automatic shifting mode, when the shift roller is in the inner slot, the shift lever is in the initial position (neutral) or M position. When the shift lever moves toward one of the gears: D, down (-), R, and up (+), the protrusion moves toward the shift roller. When the operating force is released while the shift lever is in one of the gears: D, down (-), R, and up (+), the shift hinge returns via the spring force of the shift roller unit to make the inner slot contact the shift roller, and the shift lever returns to the initial position (neutral) or M position.

[0021] When the protrusion moves toward the shift roller due to the shifting direction of the shift lever while the shift roller is in contact with the inner groove, the shift guide moves in the shifting direction and the shift spring is compressed. When the protrusion is on the shift roller, the shift protrusion contacts the side wall of the stroke groove, thereby limiting the further rotation of the shift lever in the shifting direction.

[0022] When the shift roller is in the inner slot in manual shift mode, the shift lever is in one of the following positions: initial position (N position), 5th / 6th gear selection position, 1st / 2nd gear selection position, and R gear selection position. When the shift lever is operated in the shift direction while the clutch pedal operation generates a clutch pedal signal and the travel limiter is disengaged from the brake groove, the shift roller passes through the protrusion to be fixed in the outer slot. When the shift bullet is in the outer slot, the shift lever is in one of the following gears: 1st, 2nd, 3rd, 4th, 5th, 6th, and R gear.

[0023] When the shift roller is in the inner slot in manual shift mode, the shift lever is in one of the following positions: initial position (N position), 5th / 6th gear selection position, 1st / 2nd gear selection position, and R gear selection position. When no clutch pedal signal is generated due to no clutch pedal operation, the shift hinge is allowed to rotate in the shift direction only immediately before the shift protrusion contacts the side wall of the travel groove. When the shift protrusion contacts the side wall of the travel groove, the shift hinge rotation in the shift direction is restricted by the travel brake. When the shift hinge rotation in the shift direction is restricted by the travel brake, the shift roller is located on the protrusion and is restricted from rotating toward the outer slot, where the shift signal is output.

[0024] When the shift lever is operated with the shift roller in the position of the protrusion, the shift hinge returns to its original position (N position) due to the spring force of the shift roller unit, causing the inner groove to contact the shift roller.

[0025] The shift lever's directional travel is limited to being relatively shorter in automatic shift mode compared to manual shift mode, and is also limited to being relatively longer in manual shift mode compared to automatic shift mode.

[0026] When the shift protrusion is pulled out of the stroke groove by the shift direction rotation of the stroke brake, the shift lever rotates to its full stroke, and the shift roller is located in the outer groove of the shift groove.

[0027] The electronic shift control device according to this disclosure is configured to switch between automatic shifting and manual shifting modes based on the driver's intention, thereby eliminating the simplicity of shifting operations, providing driving pleasure and improving the marketability of the product.

[0028] Furthermore, the electronic shift control device according to this disclosure is configured to limit the shift direction travel of the shift lever to different lengths depending on whether it is in automatic shift mode or manual shift mode, thereby improving the convenience of shift operation and enhancing the recognizability of shift operation.

[0029] The beneficial effects obtained from this disclosure may not be limited to those described above, and other effects not mentioned may be clearly understood by those skilled in the art to which this disclosure pertains through the following description. Attached Figure Description

[0047] The embodiments described herein will be described in detail below with reference to the accompanying drawings, and regardless of the number of drawings, the same or similar elements are given the same or similar reference numerals, so repeated descriptions thereof will be omitted.

[0048] The electronic shift control device according to this disclosure includes a mode switching device that can switch between automatic shifting operation and manual shifting operation based on the driver's intention. This eliminates the simplicity of shifting operation, thereby providing driving pleasure and improving the marketability of the product.

[0049] Additionally, the electronic shift control device according to this disclosure may include a travel limiting device that can limit the shift direction travel of the shift lever differently depending on whether it is in automatic shift mode or manual shift mode.

[0050] Typically, in automatic shift mode, the shift lever's travel distance is relatively shorter compared to manual shift mode, thus improving ease of operation.

[0051] Conversely, in manual shift mode, the shift lever travels a relatively longer distance in the direction of shifting compared to automatic shift mode, thereby improving the recognizability of shifting operations.

[0052] Additionally, the electronic shift control device according to this disclosure may include a system for implementing a mode switching device for shifting operations and a shift direction travel limiting device for the shift lever.

[0053] like Figures 1 to 27 As shown, the electronic shift control device according to this disclosure may include: a selection hinge 100 that rotates together with the shift lever 10 in the selection direction during driver operation, and has a mode conversion guide groove 110 formed on one side of the shift direction; a cover bracket 200 that covers the selection hinge 100; and a mode conversion solenoid 300 that is fixed to one side of the cover bracket 200 in the shift direction, has a first solenoid rod 310 inserted into the mode conversion guide groove 110, and is configured to move the first solenoid rod 310 within the mode conversion guide groove 110 during operation.

[0054] The electronic shift control device according to this disclosure may include: a shift hinge 400, connected to a shift lever 10, configured to rotate together with the shift lever 10 in the shift direction during driver operation, and having a shift groove 410 formed on one side in the shift direction; and a shift roller unit 500, located on one side in the shift direction, and mounted to contact the shift groove 410 under the action of a spring force. The shift groove 410 and the shift roller unit 500 can maintain constant contact during rotation of the shift hinge 400 in the shift direction.

[0055] The gear shift lever 10 may be equipped with a knob 11 and a skirt 12. The knob 11 can be held and operated by the driver's hand, and the skirt 12 is located below the knob 11 and surrounds the gear shift lever 10.

[0056] The electronic shift control device according to this disclosure is preferably located in a position that allows the driver to easily operate the shift lever 10. For example, the electronic shift control device can be installed on the vehicle's console, central dashboard, etc., and can also be installed on the seat with consideration for autonomous driving scenarios.

[0057] The lower end of the shift lever 10 passes vertically through the center of the shift hinge 400, the fixing pin 610 passes through the center of the shift hinge 400 and the lower end of the shift lever 10 in the shifting direction, and the rotating shaft 620 passes through the center of the shift hinge 400 and the lower end of the shift lever 10 in the selected direction.

[0058] The shift lever 10 is connected to the shift hinge 400 via a retaining pin 610 and a rotating shaft 620. In particular, the opposite end of the rotating shaft 620 is supported by a selection hinge 100, which serves as a central axis during rotation of the shift hinge 400 in the shifting direction.

[0059] After the shift hinge 400 is attached to the lower end of the shift lever 10, the selector hinge 100 can be attached to surround the shift hinge 400, and the cover bracket 200 can be attached to surround the selector hinge 100.

[0060] The hinge 100 can be configured as a combination of an upper hinge and a lower hinge, and the cover bracket 200 can be configured as a combination of an upper bracket and a lower bracket.

[0061] When the driver operates the shift lever 10 in the selected direction, the selection hinge 100 and the shift hinge 400 can rotate together in the selected direction.

[0062] When the driver operates the shift lever 10 in the shift direction, the selection hinge 100 does not rotate in the shift direction; only the shift hinge 400 rotates in the shift direction. Therefore, the selection hinge 100 may include a hinge groove 120 extending in the shift direction to allow the shift lever 10 to move in the shift direction.

[0063] The mode switching solenoid 300 can operate upon receiving an automatic shift mode signal or a manual shift mode signal. When the mode switching solenoid 300 operates, the first solenoid rod 310 moves forward or backward within the mode switching guide groove 110, and the travel of the selection direction of the selection hinge 100 can be variably limited according to the end position of the first solenoid rod 310 within the mode switching guide groove 110.

[0064] When the driver operates the mode selector 20, it can generate an automatic shift mode signal or a manual shift mode signal, and the mode switching solenoid 300 can be operated by receiving the automatic shift mode signal or the manual shift mode signal.

[0065] The mode switching solenoid 300 can be covered and protected by a first cover 630, which can be connected to a cover bracket 200.

[0066] The mode switching guide groove 110 includes: an automatic mode guide groove 111, in which the end of the first solenoid rod 310 is located in the automatic mode guide groove 111 in automatic shifting mode; and a manual mode guide groove 112, in which the end of the first solenoid rod 310 is located in the manual mode guide groove 112 in manual shifting mode. The automatic mode guide groove 111 and the manual mode guide groove 112 can be connected to each other.

[0067] The mode conversion guide groove 110 can be located on one side of the selection hinge 100 in the shift direction and open downward below the selection hinge 100.

[0068] The downward-opening slot in the mode conversion guide slot 110 below the selector hinge 100 can serve as the manual mode guide slot 112, and the automatic mode guide slot 111 can be formed above the manual mode guide slot 112 and connected to the manual mode guide slot 112.

[0069] The first solenoid rod 310 can move forward in automatic shift mode so that its end is located in the automatic mode guide groove 111, and can move backward in manual shift mode so that its end is located in the manual mode guide groove 112.

[0070] According to this disclosure, the automatic mode guide slot 111 can be configured to have a relatively shorter length in the selection direction compared to the manual mode guide slot 112. Therefore, the selection direction rotation stroke of the selection hinge 100 in automatic shift mode can be configured to be shorter than the selection direction rotation stroke of the selection hinge 100 in manual shift mode.

[0071] The shift control device according to this disclosure may further include: a mode switching stop 640, mounted on one side of the selector hinge 100 in the shift direction and protruding into the automatic mode guide slot 111; and a stop spring 650, configured to support the mode switching stop 640 and apply a spring force to ensure that the mode switching stop 640 protrudes into the automatic mode guide slot 111.

[0072] The mode switching stop 640 can be mounted on one side of the selector hinge 100 in the shift direction to be movable in the shift direction, and the stop spring 650 can provide spring force to the mode switching stop 640, causing the mode switching stop 640 to move in the direction protruding into the automatic mode guide slot 111.

[0073] The stop spring 650 can be constructed as a helical spring and can be installed in a pre-compressed state under the pressure of the mode-changing stop 640.

[0074] The mode switching stop 640 can be mounted to protrude at the midpoint of the length of the selection direction within the automatic mode guide slot 111, and the mode switching stop 640 can move through the first solenoid rod 310 during the rotation of the selection direction of the selection hinge 100 in automatic shift mode.

[0075] In order to make the mode switching stop 640 pass through the first solenoid rod 310 more smoothly during the rotation of the selection hinge 100 in the selection direction, the end of the mode switching stop 640 that contacts the first solenoid rod 310 may be formed with an arc-shaped cross section, but is not limited thereto.

[0076] When the mode switching stop 640 passes through the first solenoid rod 310, the mode switching stop 640 can move backward in the shifting direction. During this period, the stop spring 650 can be compressed to generate an operating force.

[0077] After the mode switching stop 640 passes through the first solenoid rod 310, the restoring force of the stop spring 650 causes the mode switching stop 640 to move forward toward the first solenoid rod 310 in the shifting direction. Therefore, the mode switching stop 640 can protrude again into the automatic mode guide slot 111, and the position of the first solenoid rod 310 can be fixed by the protruding mode switching stop 640.

[0078] In automatic shift mode, during the rotation of the selection hinge 100 in the selection direction, the first solenoid rod 310 may contact the opposite end of the automatic mode guide groove 111. When the first solenoid rod 310 contacts either end of the automatic mode guide groove 111, the rotation of the selection hinge 100 in the selection direction can be restricted.

[0079] In other words, in automatic shifting mode, the opposite ends of the automatic mode guide groove 111 can correspond to the initial position (neutral position A1) and the manual mode position (M position A2) of the shift lever 10. When the shift lever 10 is in the initial position (neutral position A1) or the M position A2, the first solenoid rod 310 is fixed in place by the mode conversion stop 640, thereby ensuring that the shift lever 10 remains stationary in the initial position (neutral position A1) or the M position A2.

[0080] Reference Figures 10 to 12 In automatic shift mode, when the selection hinge 100 rotates in the selection direction to make the first solenoid rod 310 contact the right end of the automatic mode guide groove 111, the shift lever 10 can be fixed in the initial position (empty position).

[0081] Reference Figure 10 , Figure 13 and Figure 14 In automatic shift mode, when the selection hinge 100 rotates in the selection direction to make the first solenoid rod 310 contact the left end of the automatic mode guide groove 111, the shift lever 10 can be in position M A2.

[0082] When a manual shift mode signal is generated, the first solenoid rod 310 can move backward due to the operation of the mode conversion solenoid 30, and the end of the first solenoid rod 310 can be located in the manual mode guide groove 112 where the mode conversion stop 640 is not present.

[0083] Therefore, in manual shift mode, during the rotation of the selection hinge 100 in the selection direction, the first solenoid rod 310 can move from one end of the manual mode guide groove 112 to the other end, and the rotation of the selection hinge 100 in the selection direction can be restricted when the first solenoid rod 310 contacts either end of the manual mode guide groove 112.

[0084] In manual shifting mode, the opposite ends of the manual mode guide groove 112 correspond to the 5 / 6 gear selection position B2 and the reverse (R) gear selection position B4 of the shift lever 10, respectively. Between the 5 / 6 gear selection position B2 and the reverse (R) gear selection position B4, a 3 / 4 gear selection position (initial position, N position, neutral position) B1 and a 1 / 2 gear selection position B3 can be set.

[0085] Reference Figure 10 and Figure 17 In manual shift mode, when the selection hinge 100 is rotated in the selection direction so that the first solenoid rod 310 contacts the right end of the manual mode guide groove 112, the shift lever 10 can be in the 5 / 6 gear selection position B2.

[0086] Reference Figure 10 and Figure 19 In manual shift mode, when the selection hinge 100 is rotated in the selection direction so that the first solenoid rod 310 contacts the left end of the manual mode guide groove 112, the shift lever 10 can be located in the R gear selection position B4.

[0087] Reference Figure 10 , Figure 15 and Figure 16In manual shifting mode, when the driver does not operate the shift lever 10 in the selected direction, the first solenoid rod 310 is located between the opposite ends of the manual mode guide groove 112, and the shift lever 10 can be located in the 3 / 4 gear selection position (initial position, N position, neutral position) B1.

[0088] Reference Figure 10 and Figure 18 In manual shift mode, when the selection hinge 100 is rotated in the selection direction so that the first solenoid rod 310 is located between the opposite ends of the manual mode guide groove 112, the shift lever 10 can be located in the 1 / 2 gear selection position B3.

[0089] The electronic shift control device according to this disclosure may further include: a selection guide 660, coupled to one side of the selection hinge 100 in the shift direction, configured to rotate together with the selection hinge 100 in the selection direction and supporting one end of a stop spring 650; and a selection spring 670, coupled to the selection guide 660, with one end supported by a first protrusion 130 extending from the selection hinge 100 and the other end supported by a second protrusion 210 extending from the cover bracket 200. The selection spring 670 is compressed during rotation of the selection hinge 100 in the selection direction and returns the selection hinge 100 to its initial position B1 when the selection operating force is released.

[0090] In manual shifting mode, during the rotation of the selection hinge 100 caused by the operation of the shift lever 10, the shift lever 10 can move between the 5 / 6 gear selection position B2 and the reverse (R) gear selection position B4. When the selection operation force is released from the shift lever 10, the shift lever 10 can return to the 3 / 4 gear selection position (initial position, N position, neutral N position) B1 due to the spring force of the selection spring 670.

[0091] According to this disclosure, the selector hinge 100 can be connected to the cover bracket 200 to be rotatable in the selector direction. The cover bracket 200 can have a bracket hole 220 formed on one side in the shift direction to allow the selector hinge 100 to rotate in the selector direction. The selector hinge 100 can also have a protrusion 140 on one side in the shift direction, which is inserted into the bracket hole 220 and rotates in the selector direction.

[0092] Reference Figure 12 The width D1 of the bracket hole 220 in the selection direction can be greater than the width D2 of the protrusion 140 in the selection direction. Therefore, during the selection direction operation of the shift lever 10, the protrusion 140 can rotate in the selection direction while located within the bracket hole 220.

[0093] The first protrusion 130 can be configured to protrude from the protrusion 140, and the selection guide 660 can be connected to the protrusion 140.

[0094] Reference Figure 17 and Figure 19 In manual shift mode, during the rotation of the shift lever 10 in the selection direction, when the first solenoid rod 310 contacts either end of the manual mode guide groove 112, the protrusion 140 also contacts either side of the bracket hole 220 on either side of the selection direction, which can limit the rotation of the shift lever 10 in the selection direction.

[0095] In other words, embodiments according to this disclosure are configured such that rotation is limited during rotation of the shift lever 10 in the selected direction due to the interaction between the first solenoid rod 310 and the manual mode guide groove 112, and the interaction between the protrusion 140 and the bracket hole 220. This double-stop structure provides the advantage of improved durability.

[0096] The electronic shift control device according to this disclosure may further include: a mode guide protrusion 680, configured to extend downward from the shift lever 10; and a mode guide rail 690, formed on the cover bracket 200 and configured to guide the mode guide protrusion 680 to move in the selection direction and the shift direction.

[0097] The mode guide protrusion 680 can be provided on the shift hinge 400 to protrude downward from the shift hinge 400, and can rotate together with the shift lever 10 during the selection direction and shift direction rotation.

[0098] The lower end of the mode guide protrusion 680 can be inserted into the mode guide rail 690 to move along the mode guide rail 690 during rotation of the selector direction and shift direction of the shift lever 10.

[0099] According to this disclosure, the shift roller unit 500 can be installed such that, when located on one side of the selection hinge 100 in the shift direction, one end contacts the shift groove 410, and the other end is supported by the selection guide 660.

[0100] The shift roller unit 500 may include: a shift guide 510, mounted between a shift slot 410 and a selection guide 660, movable in the shift direction; a shift roller 520, rotatably coupled to one side of the shift guide 510 and mounted to contact the shift slot 410; and a shift spring 530, mounted such that opposite ends are supported by the selection guide 660 and the other side of the shift guide 510, and configured to apply a spring force to ensure that the shift roller 520 remains in contact with the shift slot 410.

[0101] The shift spring 530 can be constructed using a coil spring and can be installed in a pre-compressed state under the pressure of the shift guide 510.

[0102] The shift control device according to this disclosure may further include: a shift protrusion 420 disposed on the other side of the shift hinge 400 to protrude in the shift direction; a travel brake 710 mounted to be rotatable in the shift direction about a brake shaft 713 relative to the selector hinge 100 at a position facing the end of the shift protrusion 420, the travel brake 710 having a travel groove 711 on one surface in the shift direction such that the end of the shift protrusion 420 is inserted into or withdrawn from the travel groove and disengaged from contact, and configured to differently limit the shift direction travel of the shift lever 10 depending on whether it is an automatic shift mode or a manual shift mode; and a brake spring 720 mounted to be supported on the travel brake 710 when fixed to the selector hinge 100, and configured to return the travel brake 710 to its original position by means of spring force.

[0103] The shift protrusion 420 can be configured to protrude from the shift hinge 400 in the shift direction in the direction opposite to the shift roller unit 500, and the travel brake 710 and the brake spring 720 can be sequentially mounted at the end facing the shift protrusion 420.

[0104] The travel brake 710 may have two brake shafts 713 protruding in the selection direction, and the brake shafts 713 are mounted on the selection hinge 100. Therefore, the travel brake 710 is rotatable about the brake shafts 713 relative to the selection hinge 100 in the shifting direction.

[0105] The shift control device according to this disclosure may further include: a shift solenoid 730, fixedly connected to the cover bracket 200 on the other side in the shift direction, and configured to operate upon receiving an automatic shift mode signal or a manual shift mode signal; and a travel limiter 750, connected to a second solenoid rod 740 of the shift solenoid 730, and inserted into or withdrawn from the brake groove 712 formed in the brake 710 during operation of the shift solenoid 730. When inserted into the brake groove 712, the travel limiter 750 restricts the shift direction rotation of the travel brake 710, and when withdrawn from the brake groove 712, the travel limiter 750 releases the restriction on the shift direction rotation of the travel brake 710.

[0106] The shift solenoid 730 can be fixedly mounted below the travel brake 710 on the cover bracket 200 and is covered and protected by a second cover 770 that can be connected to the cover bracket 200.

[0107] The second solenoid rod 740 can move upward and forward toward the travel brake 710 and downward and backward in the opposite direction during the operation of the shift solenoid 730, and the travel limiter 750 can be fixedly disposed at the end of the second solenoid rod 740.

[0108] During the forward movement of the second solenoid rod 740, the stroke limiter 750 can be inserted into the brake groove 712 formed on the bottom surface of the stroke brake 710, and at this time, the rotation of the stroke brake 710 about the rotation axis 620 in the shifting direction can be limited.

[0109] During the rearward movement of the second solenoid rod 740, the stroke limiter 750 can be withdrawn from the brake slot 712 and disengaged, and at this time, the restriction of the stroke limiter 750 on the rotation of the stroke brake 710 in the shift direction is released. Therefore, when an external force is applied to the stroke brake 710, the stroke brake 710 can rotate about the rotation axis 620 in the shift direction.

[0110] When the travel brake 710 rotates about the rotation shaft 620 in the shifting direction, the brake spring 720 can be compressed, and the travel brake 710 rotating in the shifting direction can be restored to its original state before rotation by the spring force of the brake spring 720.

[0111] The electronic shift control device according to this disclosure may further include: a shift controller 760, fixed to the cover bracket 200. The shift controller 760 is configured to receive signals from the mode selector 20 and signals from the clutch pedal 30 generated by the operation of the clutch pedal 30 (hereinafter referred to as "clutch pedal signals"), and to control the mode switching solenoid 300 and the shift solenoid 730.

[0112] Reference Figure 27 The automatic shift mode signal or manual shift mode signal generated by the operation of the mode selector 20 can be sent to the shift controller 760, and the shift controller 760 can use the automatic shift mode signal or manual shift mode signal to control the mode switching solenoid 300.

[0113] In addition, the shift controller 760 can use the automatic shift mode signal or manual shift mode signal generated by the operation of the mode selector 200 and the clutch pedal (30) signal generated by the operation of the clutch pedal 30 to control the shift solenoid 730.

[0114] When an automatic shift mode signal is generated by the operation of the mode selector 20, the shifter controller 760 can control the mode switching solenoid 300 to insert the first solenoid rod 310 into the automatic mode guide slot 111, and control the shift solenoid 730 to insert the travel limiter 750 into the brake slot 712.

[0115] Additionally, when a manual shift mode signal is generated by the operation of the mode selector 20, the shifter controller 760 can control the mode switching solenoid 300 to insert the first solenoid rod 310 into the manual mode guide slot 112, and control the shift solenoid 730 to pull the travel limiter 750 out of the brake slot 712.

[0116] The gear selection signal, generated by the selection rotation and shifting rotation of the shift lever 10, is output via the PCB 790 and then sent to the vehicle controller 40 via the shifter controller 760, whereby the vehicle controller 40 controls the vehicle's drive unit 50.

[0117] In addition, the shift controller 760 can receive acceleration and braking information of the vehicle via signals from the accelerator pedal 60 and the brake pedal 70.

[0118] In automatic shift mode, shifting is permitted when the brake pedal 70 operation signal is present. For example, shifting from D to R is permitted.

[0119] In automatic shift mode, shifting may not be allowed for safety purposes when the accelerator pedal 60 operation signal is present.

[0120] The shift groove 410 formed on one side of the shift hinge 400 in the shift direction may include: an inner groove 411, which is formed as a recessed groove in the center of a surface of the shift hinge 400; an outer groove 412, which is formed as a recessed groove on the upper and lower sides of the inner groove 411; and a protrusion 413, which is formed between the inner groove 411 and the outer groove 412 to connect the inner groove 411 and the outer groove 412, and has a cross section protruding from the inner groove 411 and the outer groove 412.

[0121] In automatic shift mode, the upper end of the travel limiter 750 is inserted into the brake groove 712, and when the shift hinge 400 rotates in the shift direction due to the shift lever 10's shift direction operation in automatic shift mode, the shift protrusion 420 can contact the side wall of the travel groove 711, thereby limiting the rotation of the shift lever 10 in the shift direction.

[0122] When an automatic shift mode signal is generated by the operation of the mode selector 20, the shift controller 760 can control the shift solenoid 730 to ensure that the travel limiter 750 is inserted into the brake slot 712.

[0123] In manual shift mode, when the travel limiter 750 is lowered due to the operation of the shift solenoid 730, the travel limiter 750 is pulled out of the brake groove 712 and disengaged. In manual shift mode, when the shift hinge 400 rotates in the shift direction via the shift lever 10, the travel brake 710 also rotates in the shift direction due to the pressure of the shift protrusion 420. As the travel brake 710 rotates in the shift direction, the shift protrusion 420 is pulled out of the travel groove 711 and disengaged, thereby allowing the shift lever 10 to rotate in the shift direction to its full stroke.

[0124] When both a manual shift mode signal generated by the operation of the mode selector 20 and a clutch pedal signal generated by the operation of the clutch pedal 30 are generated, the shift controller 760 can control the shift solenoid 730 to ensure that the travel limiter 750 is pulled out of the brake slot 712 and disengaged.

[0125] When a manual shift mode signal is generated by the operation of the mode selector 20 but no signal is generated from the clutch pedal 30, the shift controller 760 can control the shift solenoid 730 to ensure that the travel limiter 750 is inserted into the brake groove 712. In this state, when the shift hinge 400 rotates in the shift direction due to the shift direction operation of the shift lever 10, the shift protrusion 420 contacts the side wall of the travel groove 711. Therefore, the shift direction rotation of the shift lever 10 is restricted, thereby preventing further manual shifting.

[0126] Figure 21 This shows the state in which the shift roller 520 is located in the inner groove 411 of the shift slot 410 in automatic shift mode, while Figure 22 This shows the state in which the shift roller 520 is located on the protrusion 413 of the shift groove 410 when the shift hinge 400 rotates in the shift direction due to the rotation of the shift lever 10 in the shift direction.

[0127] In automatic shift mode, such as Figure 21 As shown, when the shift roller 520 is in the inner groove 411, the shift lever 10 can be in the initial position (empty position A1) or the M position A2.

[0128] When the shift lever 10 is Figure 21 When the gear shifts towards one of the following gears: D, down (-), R, or up (+), the shift hinge 400 rotates in the shift direction, causing the protrusion 413 of the shift groove 410 to move toward the shift roller 520. At this time, due to the phase difference of the shift groove 410, the shift guide 510 moves in the shift direction, and the shift spring 530 is compressed.

[0129] When the shift protrusion 420 contacts the side wall of the travel groove 711 during the shifting direction rotation of the shift lever 10 in automatic shifting mode, the shift lever 10 is restricted from further rotation in the shifting direction, and at this time, the shift roller 520 is located on the protrusion 413 of the shift groove 410, such as Figure 22 As shown.

[0130] When the shift roller 520 is located on the protrusion 413 of the shift groove 410, the shift lever 10 can be in one of the following gears: D, down (-), R, and up (+).

[0131] In other words, in automatic shift mode, when the shift bullet 122 is located in the inner groove 111a of the shift brake groove 111, the shift lever 10 can be fixed in the initial position (neutral position) A1 or the M position A2.

[0132] Additionally, when the shift lever 10 is moved to one of the gears D, downshift (-), R, and upshift (+) and the shifting operation force is released, the shift hinge 400 can return under the action of the spring force of the shift roller unit 500 (i.e., the spring force of the shift spring), so that the inner groove 411 contacts the shift roller 520 and the shift lever 10 can return to the initial position (neutral position A1) or the M position A2.

[0133] Reference Figure 23 and Figure 24 When a manual shift mode signal is generated, the first solenoid rod 310 is positioned in the manual mode guide groove 112 through the operation of the mode conversion solenoid 300.

[0134] Additionally, when a manual shift mode signal is generated and a clutch pedal signal is generated simultaneously due to the operation of the clutch pedal 30, the travel limiter 750 is pulled out of the brake slot 712 and disengaged by the operation of the shift solenoid 730.

[0135] In manual shift mode, during shifting of the shift lever 10, the shift protrusion 420 presses against the travel brake 710, causing the travel brake 710 to rotate about the rotation axis 620 in the shifting direction. As the travel brake 710 rotates in the shifting direction, the shift protrusion 420 disengages from the travel groove 711, thereby allowing the shift lever 10 to rotate fully in the shifting direction. Therefore, the shift roller 520 can be located in the outer groove 412 of the shift groove 410.

[0136] Figure 23 This shows the state in which the shift roller 520 is located in the inner groove 411 of the shift slot 410 in manual shift mode, while Figure 24 The shift hinge 400 is shown to be engaged by the shift lever 10 due to the shifting operation. Figure 21The state in which the gear shifting direction is rotated and the gear shifting roller 520 is located in the outer groove 412 of the gear shifting groove 410.

[0137] like Figure 23 As shown, when the shift roller 520 is located in the inner groove 411 of the shift groove 410 in manual shift mode, the shift lever 10 can be located in one of the following positions: initial position (N position, neutral position, 3 / 4 gear selection position) B1, 5 / 6 gear selection position B2, 1 / 2 gear selection position B3, and R gear selection position B4.

[0138] When the operating stress is released while the shift lever 10 is in one of the 5 / 6 gear selection positions B2, 1 / 2 gear selection positions B3, and R gear selection positions B4, the shift lever 10 can return to the initial position B1 due to the spring force of the selection spring 670.

[0139] Figure 24 The shift lever 10 is shown from Figure 21 The state shown is a state of rotation in the shift direction, in which a manual shift mode signal and a clutch pedal signal generated by the operation of clutch pedal 30 are generated.

[0140] When the shift hinge 400 rotates in the shift direction due to the shift rotation of the shift lever 10, the shift roller 520 is inserted into the outer groove 412 of the shift groove 410 and fixed in the outer groove 412.

[0141] When the shift roller 520 is in the outer groove 412, the shift lever 10 can be fixed in one of the following gears: 1st gear, 2nd gear, 3rd gear, 4th gear, 5th gear, 6th gear, and reverse gear.

[0142] Figure 25 This illustrates a situation where a manual shift mode signal is generated by operating the mode selector 20, but no clutch pedal signal is generated because the driver does not operate the clutch pedal 30.

[0143] At this time, the shift controller 760 controls the operation of the shift solenoid 730, causing the travel limiter 750 to insert into the brake slot 712 of the travel brake 710. Therefore, the travel brake 710 is restricted to rotating in the shifting direction due to the restriction of the travel limiter 750.

[0144] Therefore, when the shift hinge 400 rotates in the shift direction due to the operation of the shift lever 10, the shift protrusion 420 contacts the side wall of the stroke groove 711, thereby restricting the rotation of the shift hinge 400 in the shift direction and preventing further manual shifting.

[0145] In other words, when the driver operates the shift lever 10 in the shift direction while a manual shift mode signal is generated but no clutch pedal signal is present, the shift hinge 400 is only allowed to rotate in the shift direction until the shift protrusion 420 contacts the side wall of the travel groove 711, and once the shift protrusion 420 contacts the side wall of the travel groove 711, further rotation of the shift hinge 400 in the shift direction is restricted.

[0146] When the rotation of the shift hinge 400 in the shift direction is restricted by the contact between the shift protrusion 420 and the travel groove 711, the shift roller 520 is located on the protrusion 413 of the shift groove 410 and is prevented from entering the outer groove 412 for outputting the gear position signal. Therefore, no gear position signal is output, thereby preventing operational errors.

[0147] When the shifting operation force of the shift lever 10 is released with the shift roller 520 located on the protrusion 413 of the shift groove 410, the shift hinge 400 returns by the spring force of the shift roller unit 500 (i.e., the spring force of the shift spring) so that the inner groove 411 contacts the shift roller 520, and the shift lever 10 returns to the initial position (N position) B1.

[0148] The electronic shift control device according to this disclosure may further include: a permanent magnet 780, fixedly connected to a rotation shaft 620 of the shift hinge 400; and a printed circuit board (PCB) 790, fixed to a cover bracket 200 to face the permanent magnet 780. The PCB 790 recognizes the magnetic flux signal generated by the position change of the permanent magnet 780 when the shift lever 10 rotates in the selection direction and shift direction, and outputs the selected gear.

[0149] PCB 790 may include a Hall sensor configured to identify permanent magnet 780 such that when the position of permanent magnet 780 changes according to the rotation of shift lever 10 in the selection direction and shift direction, the selected position and selected gear signal can be identified and output.

[0150] As described above, the electronic shift control device according to this disclosure is configured to switch between automatic shifting operation and manual shifting operation based on the driver's intention, which eliminates the simplicity of shifting operation, thereby providing driving pleasure and improving the marketability of the product.

[0151] Furthermore, the electronic shift control device according to this disclosure is configured such that the shift direction travel of the shift lever 10 is relatively shorter in automatic shift mode compared to manual shift mode, and relatively longer in manual shift mode compared to automatic shift mode, thereby improving the convenience of operation and enhancing the recognizability of shift operation.

[0152] Although this disclosure has been described and illustrated in conjunction with specific embodiments thereof, it will be apparent to those skilled in the art that various improvements and modifications may be made to this disclosure without departing from the technical spirit of this disclosure as defined by the appended claims.
